Webcure state. The Mooney Scorch and T90 data shown in Table 3 indicate the processing additives increase the scorch safety of the compounds enhancing processability but have minimal effect on the cure time. HT276 increases T90 slightly. Each of the processing additives also provide a reduction in the Mooney Viscosity as shown in Table 3. WebSafety and Handling ... scorch is a problem, it may be necessary to withhold the curative masterbatches from the internal mixer. The masterbatches can then be added in a second pass through the internal mixer or on a mill. For additional mixing and processing strategies, consult the Chemours

Web23 Jan 2024 · Precautions for preventing scorch will be introduced. For each batch of rubber compound, based on the original data, set the range of scorch time, and continuously adjust and solve within this range. For example, set to Mooney scorch time, 125 ℃ Mixed rubber can be cooled to room temperature by water cooling, air cooling, or both. WebScorch safety (t s 2) is the time to 2 units above minimum torque (ML), cure time (t 50) is the time to 50% of delta torque above minimum and cure time (t 90) is the time to 90% of … WebThis comparison example clearly shows that an isocyanate cure has good scorch safety (Stock A).
